Azipod propulsion is recognized as a best propulzion system for drillships. It was hard for these ships to resist ocean conditions with conventional propulsion system which produced thrust just on the stern of ship because main goal for drillships is to stay at the same location. Because of that drillhips use 6 azipod propulsors which are capable to produce thrust in any direction. In this work, characteristics of drillships, parts of this ship that are specific to them and equipment they use for underwater drilling are described. It is explained how azipod propulsion system works and the way how electric power produced by the ship's generators comes to the propulsors. Drillships found the most appropriate propulsor in Azipod CZ produced by company ABB, and his characteristics and parts are also described. In closing part of this work it's decribed how dynamic positioning system, which contorls all propusors, works with help of differential global positioning DGPS and other position reference systems.
